SPECIFICATION forming part of Letters Patent No. 285,632, dated UNITED,STATES PATENT OFFICE.

ARTHUR G. LEONARD, OF NEW YORK, N. Y.

RAILROAD-"SIGNAL.

September 25, 1883.

Application filed May 8, 1883. (No model.)

To all whom it may concern Be it known that I, ARTHUR GEORGE Leon- ARD,of the city, county, and State of New York, have invented a new andImproved Railroad-Signal, of which the following is a full, -clear, andexact description.

This invention pertains to improvements in railroad-signals; and itconsists of the combination and arrangement of parts, substantially ashereinafter fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in

which similar letters of referenceindicate corresponding parts in allthe figures.

Figure 1 is aperspective viewof asemaphore and its operating mechanism,togetherwith apparatus that may be employed in carrying out myinvention. Fig. 2 is an elevation of the semaphore and itsoperating-gear and a sectional elevation of the torpedo apparatus, theworkinggear for the latter being somewhat modified. Fig. 3 is ahorizontal section of the inclosing-case of the torpedo apparatus andplan view of said apparatus. Fig. 4 is a horizontal section of thesemaphore and its working-gear and plan of the torpedo apparatus,showing another modification of the operatinggear for the latter. Fig. 5is a detail of the torpedo apparatus in horizontal section.

I propose to combine any approved or practicable apparatus or mechanismby which torpedoes may be placed on the rails with the semaphoreconnecting the working-gear of the said apparatus or mechanism with thatof the semaphore, so that whenever the semaphorelcver is shifted to setthe semaphore for danger a torpedo, or two or more, if desired, will beplaced on the rail,to sound an alarm for attracting the attention of theengineer by that means, for a safeguard against failure of attractinghim by sight of the semaphore, as may happen by various causesforexample, any

disorder to the machinery of the locomotive that may so suddenly occuras to excite such attention to it as to cause him to forget to look outfor thesemaphore.

In this case I. have represented a disk or wheel, a, located in asuitable position by'the side of the rail b,and arranged to turnhorizontally on the vertical pivot (I, said disk having means forconnecting a series of torpedo-carriers, 6, so as to project radiallyfrom its up per surface at suitable distances apart, and so that eachcarrier will swing over the top of the rail and'hold thereon a torpedo,f, when the disk is stopped in the proper place and the carrier has atorpedo on it. 7

The torpedoes may be temporarily attached to the carrier with sufficientadhesion-for being properly held by any sticky substance, as gum,varnish, and the like.

The carrier maybe attached to the disk by binding-posts and screws 9,and the disk may be turned by a ratchet, 72 and pawls z j, said pawlsbeing connected by any approved arrangement of rods, cranks, and otherdevices common to such contrivances with any part of the semaphoremechanism adapted to impart the requisite-movement to the disk whenvoperated in the usual manner for shifting the semaphore, the arrangementbeing such that when the semaphore shifts to danger the torpedo willrest on the rail, as in Figs. 1 and 2, and when the semaphore shifts tosafety the disk will assume the position in Fig. 3, in which thetorpedoes are clear of the rail, allowing the train to pass withoutgiving the signal. For this purpose I have applied the push-pawl i tothe forked slide-bar k to shift thetorpedoes forward onto the rail whenthe semaphore is set to danger, and the pullpawl j to shift the carrierfrom the rail after its torpedo has been exploded and when the semaphoreshifts to safety, and I have contrived various ways for causing theslide-bar to be shifted by the semaphore-lever Z. For instance, in Fig.1 it is connected by rod on with a bell-crank, n, pivoted on a stand, 0,and connected by rod 1) with the counterbalanced lever q of thesemaphore.

In Fig. 2 the bell-crank a is pivoted to the post 8 of the semaphore fora stand, and is connected to lever (1 back of its pivot s,insteai.of atthe front, as in Fig. 1, for the reason that bell-crank a is reversed orinverted in Fig. 2.

In Fig. 4 the bell-crank n is arranged on a separate stand, t, and alsohorizontally, so that it may be connected'with the semaphore-rod a byits rod 1).

It will be seen that so far as the working of the disk by thesemaphore-lever is concerned the mechanism may be arranged to suit thewill of the constructor or any conditions af fecting the same, and whilethe disk for placing the torpedoes on the rail is probably the best andsimplest, other forms of apparatus may be used, as a sliding pusherhaving a carrier attached and being arranged to push out the lowermosttorpedo of a column,which Willdrop into the carrier when drawn backunder the column, the carrier being contrived to hold the torpedoWithout the gum.

I propose to inelose the disk by a case, r, for protection,making aslit, 1],)Vll010 the torpedoes are to swing out over the rail, and willaxis, 1/, which is connected to the lever q by rod (1, andthe lever qwill be connected to the hand-leverl by rodf, bell-erank and theconnecting-rod a.

The inelosing-case a may be square or round, as preferred.

The slide-bar 7c is arranged in a guide-stand,

h, for its support and control in being shifted to Work the disk a; l

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is- I 1. The combination of anintermittingly-rotating disk a, torpedo-carrier c thereon, and theinclined guide 2, substantially as described.

2. The disk (1 having torpedo-carriers e, radial to and projectingfromit, in combination with the semaphore mechanism by the ratchet 71',push-pawl z, pull-pawl 7', sliding bar k, con meeting-rods m and p, andbell-crank 12 sub stantially as described.

3. In a railroad-signal the combination, with the disk (1, having theradially-projecting torpedo-carriers e, of the ratchet 71/, push andpull pawls z j, sliding bar k, connecting-rods m and p, bell-crank n,counter-balance q, rod (1, the semaphore a, crank-shaft I), lever Z, andthe mechanism connecting it to the counter-balance, substantially as andfor the purpose set forth.
